Function A Function C Function D Function B Function QEncapsulated Timer for Compressor and

heat Pump

When a compressor is stopped by the Thermostat, it should not restart immediately on full load. A timer of 3 to 5 minutes is needed to equalise the Interior pressure in the system, or to avoid a sudden drop in the latter. In other words, the timer is needed to prevant reset of the thermostat and to ensure optimal opertion of the equipment. For this application. BIL has developed a special low-cost timer with only 2 terminals, the SAS-CB (load in series with timer) Note : At the first supply "ON" the compressor starts instantaneously without loss of time

Curves

Delay on make timing commences with the supply on (S1). At the end of timing, the load R is energized.

The timer is permanently supplied. At the closure of contact S2, the load is energised until the set time has elapsed, after the opening of S2. If S2 is reclosed during timing, the output will remain energised. Command contact S2 should be isolated from any other circuit.Power supply S1 has to be closed when operating S2

The timer is permanently supplied. The load is alternativelyde-energised and energised repeatedly to the set time.Function D :Pause start cycle (Standard Supply)Function Di : Pulse start cycle

Function B :Single ShotThe timer is permanently supplied. At the closure of the command contact S2 (either fleeting or maintained contact), the load R is energized. The load de-energized at the end of timing.Function H : Interval TimerAt the closure of S1(Supply ON), the load is energised and timing starts. At the end of timing, the load de-energised

The star relay energizes when supply is applied to the timer and timing begins. After the timing, the star relay deenergises. After a pause of about 100ms, the delta relay energizes and will be maintained.
